Extract

During the course of the eighteenth century important changes occurred in the conception of matter held by British natural philosophers. Historians of science have described these changes in different ways, but certain common features can be abstracted from the more recent accounts. First, there was a movement away from Newtonian matter theory, which saw all matter as the various organizations of homogeneous particles and the forces of attraction and repulsion acting between them. In place of this theory increasing favour was shown towards a more empirical or ‘chemical’ approach to matter which assumed the existence of several essentially distinct types of matter each endowed with different specific qualities or properties. Second, there was an increasing tendency to accept activity as a property of matter itself rather than to ascribe it to immaterial forces.

6 Of course Newton himself tried to devise a purely mechanical explanation of universal gravitation in a letter to Boyle of 1679, but was later forced to abandon it. This account of Newton's ideas of matter/spirit relations is based on Newton's ‘mature’ thought, but I believe it is also consistent with his earlier views.

21 Leibniz did not of course believe with Descartes that matter is only extended substance, but he did hold that extension enters into the essence or nature of bodies; see Latta, Robert (ed.), Leibniz: the Monadology and other writings, Oxford, 1898, p. 28nGoogle Scholar.

22 On Newton's conception of nature as a perpetual worker, see Heimann, , ‘“Nature is a perpetual worker”’, op. cit. (2)Google Scholar. My interpretation of the relations between matter, spirit, and nature in the Leibniz-Clarke debate differs significantly from Heimann's treatment of these issues in his op. cit. (4). It appears to me that Heimann has not sufficiently distinguished between matter and nature in arguing that Newton denied that activity is intrinsic to the natural order (ibid., p. 273), and this leads him to the paradoxical assertions that ‘In denying that the activity of nature was intrinsic to the natural order, Newton emphasized the role of active principles … conceived as the manifestation of God's causal agency in nature’, and that ‘active principles were regarded as “general Laws of Nature” rather than as divine abrogations of the laws of nature’ (ibid., p. 274). From Heimann's own account it is clear that Newton did conceive of nature as being active, but that he did not believe matter to be so. If there was a ‘shift in theological sensibility’, as Heimann claims, then it was not from the view that activity was extrinsic to the natural order to the view that it was intrinsic to it, but from the view that all activity in nature had a spiritual cause to the view that matter itself could be defined as active substance, thus abrogating the need for spiritual agencies in nature. However, this claim itself would, I believe, be far too sweeping; see p. 108, above.

23 John Hutchinson (1674–1737) was a land steward to the Duke of Somerset who was introduced to the study of natural philosophy by John Woodward, c 1700. He claimed to have derived his own system of natural philosophy from the Bible by reading it in the original Hebrew without points. His most important ‘discovery’ was that all the phenomena of nature could be explained by reference to a mechanical fluid which he called ‘the Names’. This fluid acted in three forms which appeared to the senses as fire, light, and air. He argued that the fluid was an analogical representation of the Trinity. Fire was centred at the sun where, by its great agitation, it put the surrounding ‘air’ into the action of light which then streamed out to the periphery of the world system ‘congealing’ back into air as it did so. The outermost limits of the world were circumscribed by an impenetrable barrier of congealed atoms of light from which the air was forced back to the sun where it was once more put into the action of light. By this perpetual circulation, the original motion put into the world by God was preserved. Hutchinson used the expansive pressure of the fluid throughout the world system to explain gravity, cohesion, and many other phenomena. For further details, see Kuhn, A.

29 Ibid., p. 59. Toland argued that ‘…Matter itself cannot cohere, unless contained by some Force …’. In his Letters to Serena, London, 1704, p. 201Google Scholar, he also referred to Newton's conjecture in the scholium to definition VIII of the Principia that perhaps there is nothing absolutely at rest. He used this as part of his argument that motion is essential to matter.

30 Hutchinson, , op. cit. (24)Google Scholar, ‘A treatise of power’, v, 25, 148–9, 184–5Google Scholar. For Hutchinson it was the reverse: the power to act where He is not present was what distinguished God from mere mechanical agents.

For example, because the fluid became denser as it receded from the sun, the planets were pushed towards the sun, from the denser to the rarer medium. Light permeating the interstices of bodies was the cause of fluidity, while the pressure of the air from without was the cause of cohesion. On ‘the Names’, see n. 23, above.

37 Hutchinson used the words ‘atoms’, ‘units’, and ‘corpuscles’ interchangeably. He considered that different types of bodies were composed of corpuscles of different shapes and sizes, and he clearly thought transmutation impossible. The fluid of ‘the Names’ was distinguished from all other matter, its corpuscles being finer and not subject to gravity, since they were the cause of gravity.

95 Douglas, M., Implicit meanings: essays in anthropology, London, 1975Google Scholar, does not offer a systematic approach to the formulation of cosmologies. It is a collection of essays most of which antedate Natural symbols. Her other major work on this subject, Purity and danger: an analysis of the concepts of pollution and taboo, London, 1966Google Scholar, only deals with those societies which have a strong sense of boundary between the sacred and profane, which, as she points out in Natural symbols, by no means includes all societies. The latter work seeks also to comprehend those societies with a weak sense of boundary. It is, therefore, her most systematic and comprehensive attempt to date to examine the relations between social structure and the formulation of cosmologies.

109 It will be obvious from the above account that the classification of reality is only partly determined by social structure, since one type of social structure (strong grid) produces two different types of cosmology. The crucial factor seems to be the social experience of individuals.
